Bachmann told The Associated Press on Wednesday that voters should be concerned about Cain's reversals on abortion rights and the detention of suspected terrorists at Guantanamo Bay, Cuba. Bachmann says those should give Republican voters a reason to reconsider Cain's surging candidacy.

Bachmann says that Republicans need a candidate who has been vetted and has not shifted views. She says Cain is a first-time national candidate who could still have other surprises in his past that could derail Republicans' efforts to defeat President Barack Obama's re-election bid.
